Great Tang: The System Tricked Me into a Xianxia World

Zhang Mian was born in the twenty-first century, but the time it took him to take a piss was enough for him to transmigrate.

The damn System tricked him into thinking he'd transmigrated to a dangerous xianxia world. Who knew he'd actually arrived in the Tang dynasty!

Fuming, Zhang Mian decided to defy the System, but powerful figures kept secretly helping him complete his missions. All I want is to eat, drink, and wait for death. How did I end up being revered by everyone?
